- the above described double row tapered roller bearing 110 includes a first inner ring 103 and a second inner ring 105 .
- a plurality of tapered rollers 106 are arranged between this first inner ring 103 and the above described outer ring 102 at a determined space in a circumferential direction.
- first and second inner rings 103 , 105 are engaged with an outer peripheral face of a pinion shaft 108 by tight fit, and clamped from opposite ends in an axial direction by means of a pinion gear 111 at a distal end of the pinion shaft 108 and a companion flange 112 .
- This companion flange 112 is serration engaged with the outer peripheral face of the pinion shaft 108 , and pressed with a washer 113 A of a washer faced nut 113 which is screwed on a male thread portion 108 A of the pinion shaft 108 , in an axial direction (in a direction opposite to the direction of the arrow Z).
- the companion flange 112 which has been pressed in the axial direction with the washer 113 A presses the second inner ring 105 in the axial direction, thereby to apply a pre-load to the double row tapered roller bearing 110 , and the outer peripheral face of the outer ring 102 will be expanded in a radial direction with this application of the pre-load. In this manner, the outer ring 102 is tight fitted to the inner peripheral face of the engaging part 101 A of the carrier 101 .
- the outer ring 102 of this double row tapered roller bearing 110 is fastened to the engaging part 101 A by making its flange portion 102 A opposed to an end face of the engaging part 101 A, by aligning a threaded hole 115 formed in this engaging part 101 A with a bolt hole 116 formed in the flange portion 102 A, and by inserting a bolt 117 into this bolt hole 116 to be screwed into the threaded hole 115 .

- the pre-load is applied to the double row tapered roller bearing 110 . Due to this application of the pre-load, the outer peripheral face of the outer ring 102 will be expanded, and come into tight fit with respect to the engaging part 101 A of the carrier 101 .
- the outer ring 102 of the above described double row tapered roller bearing 110 is clearance fitted to the above described engaging part 101 A, because the pre-load in the axial direction is not applied to the bearing 110 , and accordingly, the outer ring 102 can be easily engaged with the engaging part 101 A.

- the outer ring 102 is so adapted as to be tight fitted to the engaging part 101 A when the pre-load has been applied to the double row tapered roller bearing 110 , it is to be noted that the outer ring 102 may be set so as to be transition fitted.
- the outer peripheral face of the outer ring is clearance fitted to the fixed part because the pre-load in the axial direction is not applied to the bearing, and consequently, the outer ring can be easily engaged with the fixed part.
- the outer ring in the state where the outer ring has been incorporated into the fixed part, the outer ring can be tight fitted (or snap fitted) to the fixed part by applying the pre-load to the bearing and expanding the outer ring in the radial direction.
- the method for assembling the double row tapered roller bearing assembly of the invention assembling performance will be improved, because in the above described first step, the double row tapered roller bearing is engaged with the fixed part by clearance fit. Moreover, in the above described second step, the pre-load is applied to the double row tapered roller bearing by pressing both the end faces in the axial direction of the double row tapered roller bearing, in the state where the rotation shaft has been press fitted in the double row tapered roller bearing. Due to this application of the pre-load, the outer ring of the double row tapered roller bearing is expanded in a radial direction, and the outer ring is tight fitted (or transition fitted) to the fixed part. Therefore, according to the assembling method of this invention, while enjoying favorable assembling performance of the bearing, supporting rigidity of the bearing can be also enhanced.
